WATER COOLER.

Application filed March 2, 1927. Serial No. 171,982.

'My invention relates to improvements in water coolers, and it consists in the combinations, constructions, and arrangements, hereinatter described and claimed.

An object of my invention is to provide a water cooler which is especially designed to be used in connection with. a standard refrigcrating coil and which may be connected to the coil without any alterations being necessary in the latter.

A further ob ect of my invention is toin the following specification, and the novel features of my invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawing, forming a part of this application, in which- Figure 1 is a front elevation of the device shown operatively applied to the evaporator of a refrigerating machine,

Figure 2 is a vertical section thru the device, and

Figure 3 is a section along the line 33 of Figure 2. 0

In carrying out my invention, I make use of an ice box 1 having the evaporator oi? a refrigerating machine 2 mounted therein. The water cooler? is preferably connected to the outside of the box 1 and has an endless pipe 4 projecting into the box 1 and secured to one of the refrigerant pipes 5 by means of clamps 6 or other suitable fastening devices.

Figure 3 shows the cooler as being divided into three compartments, the compartment 7 housing an insulating material 8, the compartment 9 receiving the incoming water 10, and the compartment 11 retaining the cooled water 12. The water is conveyed to the compartment 9 by means of an inlet pipe 13, and from there it enters the compartment 11 by means of openings 14. The endless pipe 4 extends vertically substantially thruout the entire length of the inner compartment 11 and carries radiating fins 15 for more quickly cooling the water.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The temperature of the pipes 5 ranges between 8 and 27 degrees Fahrenheit. The average is approximately 18 degrees Fahrenheit. The nonfreezing fluid inthe endless pipe 4 will only circulate when there is a difference of approximately 18 degrees between the portion of the pipe disposed within the compartment 11 and the portion secured to the pipe 5. It will, therefore, be seen that it will be impossible to freeze the water in the cooler since "0 the water at no time will drop below 38 degrees.

The cooling operation is practically automatic, starting when the water in the cooler is above a certain temperature and stopping when it drops below acertain temperature.

I claim:

1. In combination, a cooler box, a refrigcrating machine in the box having refrigerating coils therein; a water cooler disposed on the outside of said box, said water cooler comprising an insulated chamber, a Water receiving compartment inside of said chamber, a cooling compartment disposed inside of said water receiving compartment; an endless pipe containinga non-freezing cooling fluid extending thru said cooling compartment and being attached to the outside of said refrigcrating coils.

2. The combination with a refrigerating machine of a water cooler, and an endless ipe contacting with the evaporator of the re rigerat-ing machine and extending thru said cooler and carrying a non-freezing 1i uid; said water cooler having an insulated 0 amber, a water receiving com artment disposed I on the inside of said cham er, and a cooling compartment disposed on the inside of said water receiving compartment and around said endless pipe, said water cooler being provided 100 with inlet and outlet openings so arranged as to cause the circulation of the water around the portion of the endless pipe within the cooling compartment before the withdrawal of the water. 4

3. In combination with a refrigerator box, a water cooler disposed outside of said box and comprising a water receiving compartmcnt, a cooling compartment disposed inside of said water receiving compartment, and 110 an endless pipe carrying a non-freezing liquid, said pipe extending thru said cooling compartment and thru said box, said nonfreezing liquid being caused to circulate therein by the temperature difference between said cooling compartment and said refrigerating box, said water cooler being provided with inlet and outlet openings so arranged as to cause the circulation of the water around the portion of the endless pipe within the cooling compartment before the Withdrawal of the water.

4. The combination with an ice box, a water cooler disposed on the outside of said ice box, and a refrigerating machine disposed on the inside of said ice box, of an endless pipe contacting with the evaporator of said refrigerating machine and extending thru said cooler, said pipe carrying a non-freezin liquid; said water cooler having an insul chamber; a water receiving compartment disposed on the inside 'of said chamber; a cooling compartment disposed on the insideof said water receiving compartment and around said endless pipe; said water cooler being provided with water inlet and outlet openings so arranged as to cause the water to circulate around the portion of the endless pipe in the ated cooling compartment before being withdrawn therefrom.

5. The combination with an ice box, a water cooler dispesed on the outside of said ice box, and a refrigerating machine disposed on the inside of said ice box, of an endless pipe contacting with the evaporator of said refrigerating machine and extending thru said Water cooler, said pipe carrying a non-freer ing liquid; said water cooler having an insulated chamber; a water receiving compartment disposed on the inside of said water chamber; a cooling compartment disposed on the inside of said water receiving compartment and around said endless pipe; an inlet for said Water receiving compartment and an outlet for said water cooling compartment, said inlet and outlet being disposed at the bottom of said compartment, said compartments communicating with each other at the top of said cooling compartment, thereby causing the circulation of the water around the portion of the endless pipe in the cooling com artment.before the water is withdrawn t erefrom.

In testimony whereof I aflix my signature.

JAMES TELFORD HAMILTON.
